RESILIEN'J. TIRE.

Application filed September 18, 1923. Serial No. 663,402.

To all whom it may concern Be it known that I, CHAUNGEY M. PINoK- NEY, acitizen of the United States, residing at Denver, in the county ofDenver, State of Colorado, have invented a new and useful ResilientTire; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to makeand use the same.

The invention relates to resilient tires for use on automobile wheels,and has for its object to rovide a device of this character which wi beresilient, and which will obviate the necessity of inflating the tire,thereby obviating puncture or deflation of the tire. A further object isto provide an automobile tire comprising a circumferentially coiledspring adapted to be received on the rim of an automobile wheel, aflexible metallic band extending around the spring circumferentially anda tire casing in which the band and spring are disposed and held bymeans of the wheel flanges. The band forms means for crowding the tirecasing flanges into engagement with the wheel flanges thereby insuringpositive holding of the tire casing. The tire casing takes up theinitial shock and the other shock portion is taken up in the coiledspring and band, therefore theentire shock is taken up in the tire as awhole before it reaches the vehicle.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it bein understood that changes inthe precise em odiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of the tire, showing thesame on a wheel and partially 5 broken away to better show thestructure.

Figure 2 is a transverse sectional view through the tire and a portionof the wheel taken on line 22 of Figure 1.

Referring to the drawing, the numeral 1 designates a conventional. ormof automobile wheel and 2 the folly thereof. Disposed on the peri heryof the felly 2 is a rim 3, which rim as one of its sides provided with aflan e 4 for receiving and. hold- 5 ing the bead 5 o the tire casing 6.Secured detachably by means of bolts 7 to the opposite side of the folly2 is a removable rim section 8, which is provided with a clincher flange9 adapted. to engage the tire bead 10 and which in combination with theflange 4 securely holds the tire 6 on the rim 3 in the usual manner.

Surrounding the rim 3 and in engagement with the periphery thereof is anendless coiled sprin 11, the convolutions of which are substantiallyradially disposed, and are flexed inwardly as the automobile goes overthe ground for partiall taking up the shock. Surrounding the coile sprinis a metallic casing 12, preferably forme from spring material, withwhich metallic casing the inner wall of the tire casin 6 engages. Thetire casing 6 is formed 0 rubber and partially takes up the shock as thewheel goes over rough ground, however the shock which is not taken up bythe rubber tire casin 6 is taken up by the metallic casing 12 anfl thecoiled spring 11. As the tire is compressed, the metallic casing 12 istransversely spread and its sides 13 are forced outwardly, therebycrowding the beads 5 and 10 into close engagement with the clincherflanges 4 and 9, thereby insuring a positive holding of the tire casing6 at all times.

From the above it will be seen that a resilient tire is provided forautomobile wheels, wherein explosions of the tire incident to uncture isobviated, and one wherein inflatmg the tire is eliminated and the tireconstructed in a manner whereby upon puncture of the same the resiliencyof the tire will not be affected. It will also be seen that a coiledspring and a metallic casing is used for partially taking up the shock,and that by eliminating the inflation feature, the tire casing 6 may beused until the tread portion thereof is worn through if so desired,there b reducing the cost of upkeep of automobiles, as far as tires areconcerned, to a minimum.

The invention having been set forth what is claimed as new and useful is1- The combination with an automobile wheel, a rim surrounding saidwheel, a detachable ring, clincher flanges carried by the detachablering and the rim, of a tiredisposed on said rim, said tire comprising atire casing, clincher beads carried by said tire casing and with whichthe clincher flanges engage, an endless coiled spring sur rounding therim and in engagement therewith and having its convolutionssubstantially radially disposed, a yieldable metallic casing extendingaround the coiled spring, the adjacent sides of said yieldable metalliccasing being disposed adjacent the clincher beads and periphery of thedetachable ring and forming means whereby upon a compression of the tirethe clincher beads will be forced outwardly into engagement with 10 theclincher flanges.

In testimony whereof I have signed my name to this specification in thepresence of two subscribin Witnesses.
